Gold processing | Britannica
The gold was concentrated by washing away the lighter river sands with water, leaving behind the dense gold particles, which could then be further concentrated by melting. By 2000 bc the process of purifying gold-silver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense …
Understanding efficient process ... - Mining …
In order to get to the gold when mining, operators first have to shift a considerable amount of dirt. It roughly works out that 3g of gold is recovered for every tonne of dirt mined. Although the ratio for gold to dirt is relatively small, the metal’s status as a high-value product justifies such processes.
